XMLHttpRequest: responseURL property
Note: This feature is available in Web Workers, except for Service Workers.
The read-only XMLHttpRequest.responseURL property returns the serialized URL of the response or the empty string if the URL is null. If the URL is returned, any URL fragment present in the URL will be stripped away. The value of responseURL will be the final URL obtained after any redirects.
Example
js
const xhr = new XMLHttpRequest();
xhr.open("GET", "http://example.com/test", true);
xhr.onload = () => {
console.log(xhr.responseURL); // http://example.com/test
};
xhr.send(null);
